Q Explain me full sign convention for mirrors and lenses...



( BOTH CONVEX AND CONCAVE LENS AND MIRROR..)


CLASS 10TH PHYSICS NCERT OR CBSE..

With good and understandable manner... !!


Q → : And also tell me that : if magnification of concave mirror / convex mirror is in negative then the image formed will be real and inverted and when magnification of concave mirror / convex mirror is in positive then the image formed will be erect and virtual..... In convex lens and concave lens its have same magnification like concave mirror / convex mirror...??

( Main question is that : The magnification in lens is same as mirror..???? or its different..??? )

Answer 1

$<b><i>Sign convention for spherical mirrors:</b>$

Object is always considered at the left of mirror

Distances measured along y-axis above the principal axis are taken as positive and that measured along y-axis below the principal axis are taken as negative.

Distances measured in the direction of the incident ray are taken as positive and the distances measured in the direction opposite to that of the incident rays are taken as negative.

All distances are measured from the pole of the mirror.

$<b>Sign convention for spherical lenses:</b>$

All distances measured above the principal axis are taken as positive. Thus, height of an object and that of an erect image are positive and all distances measured below the principal axis are taken as negative.

The distances measured in the direction of incident rays are taken as positive and all the distances measured in the direction opposite to that of the incident rays are taken as negative.

All distances on the principal axis are measured from the optic center.
